DANIEL M. KCHTA AND FRANK BAnLoU, 0F BROOKLYN, NEW Yeux;

sTnIKnG-MACHINE.

Application inea April as,

To all Aw hom it may` concern Be it known that we, DANJEL Ml KUCHTA and FRANK BALLoU, both citizens of the United States, residing at` the borough of Brooklyn, city of New Yorin -countyfof Kings, and State of New York,` have invented certain new and useful Improvements in Striking-Marchinos, of which the following is a specification, reference `being had therein to the accompanying drawings, which tori-n a part thereof.

Our invention relates to striking machines, and more particularly to a type thereof in which compressed air is used asthe medium for registering the `force of the impact of a mallet or other implement with the anvil block. Y

ln a machine made inaccordance with our invention', we employ a registering mechanism capable of indicating-the' orce otra blow upon a -depressible anvil head, said mechanism being` differentially operative through the medium of air pressure developed by the movement of a piston carrying said anvil head and mounted in a cylinder' "from which the 'air under a pressure determined by the torce of a blow upon said head or the rapidity of the descent of the piston, is conveyed to the actuating means for said registering mechanism. Inthis manner it is possible to register the comparative force of dillerent blows upon said anvil head with sul'licient accuracy for the purpose of a machine lwhich designed tor use merely as an amusement device, and not tor determining, with any degree'of scientific accuracy, the torce of the blow delivered.

A machine made in accordance with our invention has the advantage that it possesses more or .less mystery as to its mechanisms thus tending to arouse the curiosity of the public with agconsequent incentive to its extensive use.

Striking machines heretofore extensively used have employed a structure somewhat oi the nature of a catapult, in which a Inova-ble weight, slidably mounted upon a vertically extending wire, has movement with relation to a graduated vertical scale, the comparative force of succeeding blows beingr determined by observing the movement oi the projectile, which `descends suliiciently rapidly to prevent any accuracy in determining the elect of the blow.

In device made in accordance with our Speci'catonof Letters Iatent. Patented J 1L 18, 1921 1920. serial No. 377,305.

invention, there will be a slight dwell of the dial linger of theregistering mechanism, andV a `more or less slow returnto normal. so as to permit a more or less accurate readl ing ofthe dial. i

'Associated with the registering mechamsm is a compressed air actuated gong so connected with the same `source of power as VOperates the registering mechanism, als to cause the sounding thereof with each `actuation ofthe machine and substantially simul taneously with the actuation ofthe registering mechanism.

While it is essential to provide restoring means for the piston so as to permit the automatic return oi the various working parts to their normal. positions, the construction and arrangement ofparts is such that the registering and the 'gong mechanisms will be restored to n'ormal'through gravity,'t'he `air flowing tothe vcylinder `upon the intake stroke ot' the piston momentarily retarding the return movement of the registering mechanism so to permitthe reading of the record as to the force `olf the blow struck.

The actuating means for the registering mechanism and for the gong are so constructed that these mechanisms will berresponsive only to a sudden developmentof ipressure, a gradual development ot such pressure having substantially no operative effect upon these machanisms.

We also provide means'in each oi the air lines from the cylinder to the `dial finger actuating mechanism and the 'gong striker actuating mechanism, which will cause the developmentof the desired pressure in the cylinder and its :effective application to said mechanisms, while permitting adjustment which will regulate the power applied to these mechanisms to securethe desired operative effect thereon.

The machine is so constructed that' the registering mechanism will be but a short distance from the grouhd,thus bringing this mechanism sufficiently close to the user to add attractiveness to the character of the machine.

In conjunction with the registering mechanism, we providea counter adapted to be `actuated through the same agencies actuating theA said mechanism; thus automatically recording the number of `times the machine has been actuated and providing a positive check-upon the carnage `of the machine, so

as to protect the owner thereof from possible pilfering.

The construction of the machine is so simple throughout, that it will not become disarranged from the hard use to which a machine of this character is subjected, while permitting an inexpensive production of the machine, andv theV use of standard fittings and equipment. l f

The invention consists primarily in a striking machine embodying therein a cylinder having `a vertically extending bore, a pistonmounted therein, a piston rod sury,mounted byan anvil head eXteriorly of said cylinder and having a loose fit in the cylinder head, a registering mechanism consisting of a dial and a movable dial finger associated therewith, a pipe line leading from saidcylinder and terminating adjacent said dial, a plunger cap slidably Vmounted upon the end-of said pipe line adjacent said dial, and operative connections between said plunger cap and said dial finger, whereby the sudden development of pressure in said cylinder as a result of a blow upon said anvil head, and the resultant movement of said piston, will actuate said plunger cap and transmit movement to said dial linger proportionate to the pressure developed in said cylinder; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, andmore particularly pointed out in the-claims hereto appended.

Referring to the drawings,

Figure l is a side view in vertical section of a machine made in accordance with our invention; and

Fig. 2 is a front view of the registering mechanism with the dial broken away and the front of the casing supporting same, removed, to disclose the detailed arrangement of the actuating means for said mechanism.

Like letters refer to like parts throughout both of said views.

In the embodiment of our invention shown lin the drawings, we employ a platform a having at one end thereof a cylinder b having a vertical bore, and provided with an upper head having a central bearing opening therein. Mounted in said cylinder is a piston c, the stem c of which is provided with an anvil head c2 preferably having a cushioned top of soft rubber to prevent the jarring of the user of the machine and avoid any substantial noise in its operation. The piston c is normally thrust upwardly by means of a coiled spring 0l within the cylinder Also mounted upon the platform a is a housing e having a hinged rear wall c so as to permit ready access to the working parts within said housing. The upper part of` this lhousing is circular and the front thereof is closed by a dial face e2 having any desired arrangement of numbers thereon for indicating the force of a blow. Extending transverselly of this enlarged head is a cross beam f. jivotally mounted between said cross beam f and the dial face cL is a pinion g carried by and rotatable with a shaft f. Carried by said shaft is a dial linger g disposed between the dial face c2 and a light of glass c3 protecting the dial face and finger.

Ieading from the bottom of the cylinder is a pipe line 7L terminating below but adjacent the cross beam f, and opening inwardly of the casing e.

Slidably mounted upon the end of said pipe line and inclosing same for a suiieient distance to insure the desired extent oi' movement thereof, is a plunger cap It actuating a rack k2 meshing with the pinion g. In the form of the invention shown, this rack is a straight reeiprocatory rack having movement in the guide way f2 carried by the cross head f. Acting upon said rack is a spring its supplementing the action of gravity upon the cap L in restoring said cap and the dial finger to normal after each actuation of the piston c. By properly proportioning the diameter of the pinion g and the length of movement of the plunger cap It',

any desired range in the operation ofY the machine may be secured.

In order to have a check upon the operator of the machine, we mount an ordinary ratchet register j above the cap /r with the actuating Ystem thereof in the path of movement of said cap, so that said register will be actuated with each up *ard movement of the cap as the result of the development of pressure in the cylinder 7) due to the force of :i blow upon the anvil head c2.

In order to set the device to secure the desired extent of movement of the cap 71. with the development of a given pressure in the cylinder b, I provide a pressure reducing valve m in the length of the pi pe line 7L so as to permit the setting of the machine to secure any desired movement of the dial linger g ith a given pressure in said cylinder.

Also leading from the cylinder is a second pipe line n extending vertically through the casing c and terminating adjacent the top thereof. Surmounting the end of said pipe line is a plunger cap a which serves as a striker member operative with relation to a gong n2 preferably mounted above the casing e, but in close proximity to the top thereof, the striker plunger cap u being so closely mounted in relation to said gong as to insure the sounding of the latter with each down stroke of the piston c. In order to seeure the desired operative effect of said striker plunger cap, I provide a pressure reducing valve o in the length of the pipe n.

The piston stem c l as a suflicientljv loose it in the bearing in the cylinder head b to cylinder as -a result of a blow upon said anvil head, and `the resultant movement of said piston, will actuate said plunger cap and transmit movement to said dial finger ,proportionate to the pressure developed in said c linder.
